Commonly Used Processing Processes of Hematite - Xinhai

Feb 12, 2021  Commonly used hematite combined processing processes are as follows: 1. Weak magnetic-gravity-reverse flotation process. This method is to screen out most of the higher quality primary ore from the raw hematite ore by weak magnetic separation or gravity separation. The remaining ore with difficult separation is processed by reverse flotation.
